Misfire - fr 3 plugs brown. rear3 black ?

[MOM]

Hi.
My t350 has just developed a misfire from idle. Just looked at the plugs & the front 3 are a nice light brown & the rear 3 black. (No 4 wet with fuel)
I this normal ?
Does the coilpack work in 2 halves ?

Thanks for response. Dont think its flooded as does start.

Hi. Is the software easily available ?

[MOM]

I will get the diagnostic cable but now do think its the rh lambda sensor as looked at the varley bible & seems to make sense as each of the 2 sensors looks after 3 cylinders front to rear. Just wish i could get underneath to check 3 wire or 4. Its a nov 03 car. Where best to buy from....seems a big difference in price ?

[MOM]

Good advice thanks. Realised i have a very local outfit who have the software (scole engineering).
Interesting that the injection is also 2 sets of 3. I did have a quick look but dont suppose they have seperate fuses ?

Thanks for all this. I am currently struggling trying to get the pc to talk to the mbe through the 3 pin. Will post when i have a breakthrough

Thanks. Have just posted update in the new software thread with a screenshot.
.
now connected but need advice on throttle pot reset

[MOM]

Update: thanks for everyones help. Have just fitted new tps to rear(456) & was much easier than i thought it was going to be. Reset throttles on software & after about 2 mins everything sorted out nicely. Just to note after i reset throttles the adaptive cut in on 123 . Hadnt before even with fault & then errored. But switched off & cleared it & then it settled down.
Thanks again & love the software. Def be interested in a small board diagnostic unit.
